technical field

The utility model belongs to the field of medical appliances, in particular to a cervical tube sampler.

Background technique

With the progress of research on the microecology of the female reproductive tract, studies have found that the female reproductive tract is bottom-up, and there are bacterial colonization symbiotic with the human body in the vagina, cervix, uterine cavity, fallopian tubes, and pelvic-abdominal cavity. The stability of female reproductive tract microecology is closely related to the relationship between female reproductive tract diseases, which is a current research hotspot. The female cervical canal, as the boundary point between the vagina and the uterine cavity, is significantly different from the latter two in terms of anatomy and composition of epithelial cells. Therefore, the micro-ecological environment of the cervical canal is significantly different from that of the vagina and uterine cavity. It can be used to study and predict female reproductive tract diseases. To obtain cervical canal samples for research on the microecology of the cervical canal, the first thing to solve is how to avoid contamination from the vagina during the sampling process. However, how to avoid contamination of the cervical canal by vaginal microorganisms and make the samples truly reflect the microecology of the endocervical canal is an unresolved problem.

Utility model content

Therefore, the purpose of this utility model is to provide a kind of cervical canal sampler, use overtube to insert cervical canal through vagina, cervix external opening, the sampling head that is used for sampling enters cervix canal from this overtube and takes a sample, can avoid vaginal contamination Obtain cervical canal samples to ensure the stability and reliability of the microecology of cervical canal samples.

In order to achieve the above object, the utility model provides a cervical tube sampler, comprising a sampling push rod and an outer sleeve, one end of the sampling push rod is provided with a sampling head; the outer sleeve is a hollow cylindrical straight tube with an inner diameter larger than the The diameter of the sampling head, the outer sleeve is movably fitted on the sampling push rod and covers the sampling head.

Preferably, sterile fluff is provided on the surface of the sampling head. The sampling comfort is good, and the sample volume obtained is sufficient.

Preferably, the outer tube has a length of 110-120mm, an inner diameter of 5-6mm, and a scale of 0-30mm at one end. The length of the sampling push rod is 140-150 mm, the length of the sampling head is 15 mm, and the end of the sampling push rod away from the sampling head is provided with a scale of 0-30 mm. The sampling push rod is provided with a clip at the same length as the outer sleeve, that is, the sampling push rod is provided with a clip at 110-120 mm (the clip can prevent the push rod from being pushed into the cervical canal in advance). The external opening of the female cervix is 10-15mm, and the length of the female cervical canal is about 25mm-30mm. The length of the outer sleeve is designed according to the general length of the female vagina. When one end of the outer sleeve reaches the position of the cervix, the scale reading of the outer sleeve is 10-15mm. At this time, the clamp is removed, and the sampling head is pushed into the cervical canal. The rod is graduated to read 10-15mm. Set the length of the outer casing, sampling push rod and sampling head, and set the reading scale, so that the sampling standard can be implemented according to the reading when sampling is convenient. Sampling is more accurate and faster.

Preferably, the sampling push rod is provided with a disassembly crease at a position 20 mm away from the sampling head. After sampling, the sampling head can be disassembled along this crease, which is convenient for removing the sampling head for subsequent inspection.

Preferably, the diameter of the sampling head is 4-5 mm, and the diameter of the sampling push rod is 2-3 mm. The diameter of the sampling head is suitable for sampling in the endocervical canal without causing too much discomfort.

Preferably, the outer sleeve is made of soft plastic. The soft plastic can be soft plastic such as PP or PE, which is soft and comfortable for the patient, which is conducive to improving the sampling success rate.

Preferably, the material of the sampling push rod and the sampling head is hard plastic. The hard plastic is hard plastic such as hard PE. When sampling, the sampling head needs to exert a certain force on the cervical canal, and this force needs to be applied at the other end of the sampling push rod. In order to ensure the force Pass, so take hard plastic.

The beneficial effect produced by the utility model is that: the overtube can isolate the sampling head from the vagina, and avoid the influence of vaginal microorganisms on the cervical canal sample. The sampler has a simple structure, is economical and practical, has a simple and easy operation method, and is convenient for clinical popularization.
